1.1 Handheld Converter Overview
The SFX150 Handheld Converter is ergonomically designed for comfort, and ease of use,
to enable ultrasonic processing of up to 150 W at 40 kHz for quiet operation. The
converter's recessed pushbutton provides assurance against unintended activation, while
it's LED indicator provides visual feedback on the converter's operation, letting you know
when ultrasonics are being delivered by illuminating during an ultrasonic cycle or by
flashing on and off for System Error/Alarm conditions.
NOTICE
The Handheld Converter is only compatible with the SFX150 Sonifier
power supply and SFX150 microtips.
NOTICE
SFX150 software version must be V1.3 or higher for proper handheld
operation. If a previous version is installed, it must be upgraded
before using the handheld converter.
To check the software version, verify Register 1, see section 6.4
System Configuration Registers in your Sonifier power supply
instruction manual for information on accessing the configuration
registers. See section 1.4 How to Contact Branson in your Sonifier
power supply instruction manual for information on getting your
software upgraded.

1.2 Handheld Converter Setup and Operation
To set up and operate the handheld converter, take the following steps:
NOTICE
The handheld converter is only compatible with microtips. See Table
C.1 Accessories in your Sonifier power supply instruction manual for
more information.
NOTICE
Microtips are operated at high material stress levels. For this reason
Amplitude is automatically limited to 70% for Handheld converters to
mitigate the possibility of failure. To override this limit, change
Register 17 to 0. See section 6.4 System Configuration Registers in
your Sonifier power supply instruction manual for more information.
Table 1.2 Handheld Converter Setup and Operation
Item Description
1 Ensure the Sonifier power supply is turned off.
2
Connect the microtip to the handheld converter:
• Clean the contacting surfaces of the handheld converter and microtip, and
remove any foreign matter from the threaded stud and threaded hole
• Thread the handheld converter stud into the microtip and tighten, using
wrenches. The recommended torque is 220 in·lb (24.85 N·m)
3Connect the RF and D-sub cables to the Sonifier power supply as shown
on Figure 1.2 Handheld Converter Setup.
4 Turn on the power supply.
5 Select your desired operation mode.
6Perform an ultrasonic test as described on 1.3 Handheld Converter
Ultrasonic Test.
7 Press the handheld converter pushbutton to start an ultrasonic cycle.
NOTICE
The RF Connector has a set screw which must be fastened in order to
secure the connector using an Allen wrench, and loosened before
removing the RF Connector.

Figure 1.2 Handheld Converter Setup
CAUTION General Warning
Both the D-sub and RF connector must be connected and locked to
ensure proper operation.
NOTICE
In normal operation, the LED indicator will illuminate for the complete
ultrasonic cycle. In pulsed sonic modes, the LED will remain on during
both On and Off times.
NOTICE
If an Alarm/Error occurs, the LED indicator will flash on and off to
alert you. Review the error code shown on the display and consult
section 7.4 Alarms/Errors in your Sonifier power supply instruction
manual for more information. Press the reset key to reset Alarms/
Errors.

1.3 Handheld Converter Ultrasonic Test
The Test key on the front panel of the SFX150 power supply is used to verify that the unit
is functioning (providing ultrasonic energy to the converter and microtip). The test key on
the power supply must be held, and then the pushbutton on the handheld converter must
be pressed for the system to perform an ultrasonic test.
Before testing the SFX150 system, always make sure that the microtip is not touching
anything. The system also performs several self-tests when it is first turned on.
Table 1.3 Ultrasonic Test
Step Do this... To obtain this result
1
Set up the SFX150 system following the
instructions in this manual.
If no microtip is currently installed,
mount the microtip to the handheld
converter. See 1.2 Handheld Converter
Setup and Operation for more
information.
Prepare the SFX150 system to
operate, if it was not previously
assembled.
2
After you have connected the microtip to
the handheld converter and verified all
other connections are as indicated in
Chapter 5: Installation and Setup in your
Sonifier power supply instruction
manual, turn on the unit and observe the
self-test displays.
Verify that the system passes all its
self-tests, observing that there are
no error messages on the front
panel display.
The SFX150 system advances to the
ready (rdy) mode and shows 'rdy'on
the display (see section 2.2.1
Sonifier Power Supply Front Panel
on your Sonifier power supply
instruction manual).
3
Adjust the Amplitude control to
approximately 50% (observe the value
on the front panel display). See Chapter
6: Operation in your Sonifier power
supply instruction manual to adjust the
amplitude.
Ensures that ultrasonic amplitude
will be at a mid-range value, and will
not cause damage if you were using
a microtip (which must be used at
less than 70%).
4
Verify that the microtip is not touching
anything.
Press and hold the test key on the front
panel of the power supply, then press the
handheld converter pushbutton. Observe
the front panel display.
Verifies the ultrasonic output of the
system. You may hear a soft, high-
pitched sound.
The display will show the output
power value. The test will run for 2
seconds, then stop.
5
If no alarms occurred during the Test,
you may either proceed with using the
system or turn the unit off. If an error
occurs, see section 7.4 Alarms/Errors in
your Sonifier power supply instruction
manual for more information.
Verification that the SFX150 system
is operating and is ready to be set
up for your experiment or
processing needs.
NOTICE
See section 7.3 Troubleshooting Chart in your Sonifier power supply instruction manual
if you have difficulties performing the above steps.
